An evidence review of international research suggests widespread misconceptions within the medical community about early milk production, pacifiers and breast pumps may be undermining breastfeeding success in the critical first days after birth.

Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumours and identified distinct neighbourhoods of proliferating and dormant cells. The study, published in Genome Medicine, reveals that protective immune and connective cells surround the hibernating cancer cells, potentially shielding them from treatments. It suggests future therapies may need to target not only different cancer cell states, but also the local environments that help them survive, to both halt tumour growth and prevent cancer coming back later.
